Ielasi Tuned Nitro21WC & Nitro12WC US Edition engines

Coming from Ielasi Tuned are two new engines in the form of the Nitro21WC US Edition and the Nitro12WC US Edition. Both are based off of their respective WC Edition counterparts, with whom they share their outer setup, but they have been renamed after the recent tests in the U.S. that saw some internal updates to further increase the performance of the .21 1/8th and .12 1/10th Touring engine.
